From a certain perspective they get what they deserve. I am going to great lengths to "educate" DW. She is more than happy to let me do it all but then frets about not knowing what's going on when I point out to her that no one on my side of the family made it past 85 (and few over 70). On her side, over 75% made it over 85. They may rot in a nursing home but they live far longer.It's rather pathetic that in this day and age the wives' "plan" is simply to abdicate all responsibility for their financial futures to their respective husbands, and subsequently to their friends' husbands.
Part of my plan is to actually train my children. Set up a simple asset allocation method and count of DW or my children to manage it until it becomes an inheritance. If I make it to 70, I also plan to turn it over to them to manage because of all the damage I've seen the elderly do to themselves (both sides) when they get on in years.
